Mercury I/O Hydraulic Lift Arm Anodes - Zinc, Mercury Outdrive Alpha Lift Arm Anode

Alpha and Bravo zinc anodes mount on, and protect, the casing of the hydraulic rams that lift your outdrive out of the water.
They are notoriously difficult to install so Sea Shield has re-designed them to be much easier to install than competing models.
No more hidden fasteners in hard-to-reach locations, these use a thin permanently installed aluminum mounting bracket/adapter plate, which bolts to the lift arm using the original hole pattern.
The replaceable zinc or aluminum anode then easily installs on the bracket with only a single, easily accessible screw.
A clever mating design keeps the anode firmly in place, in spite of being held by just one fastener.
Good conductivity is ensured by an internal stainless steel insert, which also prevents stripping the threads when tightening.

• Anode is secured by an "underwater friendly" hex-drive (Allen head) socket screw

• All Sea Shield zinc anodes are built to military specification MIL-A-18001
• Made in California, USA
• Fisheries will continue to make the original alpha and bravo anodes available (see table)
